Hello All,

The attached patch, to trunk rev 152849, add a PLUGIN_PARSED_UNIT event,
invoked at start of cgraph_finalize_compilation_unit after all the 
compilation unit has been parsed.

My intuition is that we should better provide a little more hooks, 
especially at a such higher level. Doing everything only in passes is 
not practical (and was the reason to add stuff like PLUGIN_FINISH_UNIT

gcc/ChangeLog:

2009-10-15  Basile Starynkevitch  <basile@starynkevitch.net>
	* doc/plugins.texi (Plugin callbacks): added PLUGIN_PARSED_UNIT.
	* cgraphunit.c (cgraph_finalize_compilation_unit): Added
	invocation of PLUGIN_PARSED_UNIT callbacks.
	* gcc-plugin.h: Added PLUGIN_PARSED_UNIT.
	* plugin.c (plugin_event_name): Added PLUGIN_PARSED_UNIT.
	(invoke_plugin_callbacks): ditto.

I am bootstrapping it right now on x86_64-unknown-gnu-linux for c&c++

Comments are welcome.

I also believe that we should have plugin hooks for builtins.

Regards.
